Plasma displays

Structurally a plasma display panel is made up of a series of wells bonded between 

The conditions required for the construction of these cells place considerable strain on the phosphors. This is because setting up the transparent electrodes requires annealing in the range 500-600 °C. Additionally the phosphors must be able to stand the constant ion bombardment from the plasma and VUV radiation. Most importantly, the phosphors must convert the VUV into visible light with maximum

An LCD is a ubiquitous electronic display. Now, it is widely distributed among human daily life, like mobile phones, TV, and personal computers. The LCD has, however, a drawback, i.e., slower response than a plasma display or an electroluminescene display. Recently we have first succeeded in combination of a nanoparticle technology with the LCD technology, which realized fast response of the LCD [45,235,236]. Thus we have found a phenomenon, i.e., a frequency modulation of the LCD doped with metallic nanoparticles. Since the frequency modulation, or electro-optic property depends on the kind of metals, we have prepared AgPd bimetallic nanoparticles protected with a typical liquid crystal molecule, 4-cyano-4 -pentylbiphenyl (5CB) to investigate the electro-optic property [45,235,236]. 

Plasma displays are based on the use of lamp phosphors which have been investigated for over 60 years. Optimization for plasma display panels (PDPs) has only taken place in the last few years and there is much room for improvement.

The performance of AMOLEDs is improved drastically in the past years. In contrast to the data shown in Table 1.2 (which representing development stage in 2002), a set of recent data of a 14.1" WXGA AMLCD made with solution-processed OLED emitters is shown in Table 1.3 [163,175,176], The color gamut is improved to over 60% with respect to NTSC. The luminous and power efficiencies at white point (x 0.28, y 0.31) are >8 cd/A and >5 lm/W. The power efficiency surpasses the performance of AMLCDs, plasma displays, and all other known flat-panel displays in commercial market or under development. A photo of the 14.1" AMOLED display is shown in Figure 1.25b. 

As mentioned in this review, AMPLEDs are especially attractive for motion picture applications. The Pay-Per-View effect in OLED displays reduces power consumption and extends operation lifetime. Motion picture applications also minimize image retention and optimize display homogeneity. AMOLED has been widely viewed as a promising display technology in competing with AMLCD and plasma displays. The dream of using organic semiconductor films for optoelectronic device applications has become a reality.

Zn orthosilicate ZUjSiO iMn is a green phosphor (X 525 nm) used in fluorescent lamps, CRTs and plasma display panels. It demonstrates a low resistance to bum out, is excited by low-energy electrons and shows a linear increase in brightness with electron beam intensity. YjSiOjiCe is a highly resistant blue CRT phosphor used in projection TV tnbes (X 400 60 nm depending on the Ce content). 

Photoluminescence is a term widely applied to the range of phenomena where light emission occurs from a material after energising by photons. In this section of the book the term is specifically applied to the cases where luminescence occurs after the interaction of luminescent materials with narrow band, higher energy ultraviolet radiation, namely in lighting and plasma display panel applications. 

Organic light-emitting devices (OLEDs) are one of several technologies competing for the market for next-generation emissive flat panel displays. It is the one most likely to triumph over field emission displays (basically CRT technology in miniature) and plasma display panels.

Many applications of lanthanide materials make use of the 4f 15d excited configuration. These applications include scintillator materials, VUV lasers, and phosphors for fluorescent lighting and plasma displays (Blasse and Grabmaier, 1994 Feldmann et al., 2003). An understanding of these states is crucial to the development of advanced materials. 

DBDs are nonequilibrium plasmas at atmospheric pressure with applications in ozone generation, surface modification, pollution control, excimer lamps, and recently also in flat plasma display panels (Kogelschatz, 2003). Typical planar DBD configurations are shown in Figure 2. They have at... 

The Nu Instruments Nu Plasma displays some general similarities to the P54, but critical features are radically different in concept. Most importantly, the instrument deploys novel variable dispersion ion optics that are applied to the ion beams exiting the magnetic analyzer, permitting the use of fixed multiple collectors and rapid peak switching. 

Panasonic is still a front runner in the field of lead-free challenges. It has announced that lead was now elimnated from their plasma display panel (PDP), which is currently one of the exceptional items of RoHS Directive.
